Electricity and Heat Production (25% of 2010 global greenhouse gas emissions): The burning of coal, natural gas, and oil for electricity and heat is the largest single source of global greenhouse gas emissions. The temperature record of the last 2,000 years is reconstructed using data from climate proxy records in conjunction with the modern instrumental temperature record which only covers the last 170 years at a global scale. In 2018, China … Meanwhile, household costs are rising, and the world has continued on its path of global warming. ; Industry (21% of 2010 global greenhouse gas emissions): Greenhouse gas emissions from industry primarily involve fossil fuels burned on site at facilities for energy. According to their datasets, October 2015 was the hottest month since global records began. Most of them also have large populations and economies, together accounting for over 50% of the global population and almost 60% of the world’s GDP. Paleoclimatic Data for the Last 2,000 Years . But why should we care about one degree of warming?
